The NEECHAM Confusion Scale offers a reliable method for assessing acute confusion in elderly patients. This validated tool aids in early detection and monitoring of confusion during hospitalization.

Area of Science:

  • Geriatric Medicine
  • Neuroscience
  • Clinical Assessment Tools

Background:

  • Acute confusion is a common and serious complication in hospitalized elderly patients.
  • Early and accurate assessment is crucial for timely intervention and improved patient outcomes.
  • Existing assessment tools may lack the sensitivity or practicality for rapid bedside use.

Purpose of the Study:

  • To develop and validate the NEECHAM Confusion Scale for rapid and unobtrusive assessment of acute confusion.
  • To evaluate the reliability and validity of the NEECHAM scale in elderly hospitalized patients.
  • To identify the key domains contributing to acute confusion as measured by the NEECHAM scale.

Main Methods:

  • Development and testing of the NEECHAM Confusion Scale in two independent samples of elderly patients (N=168 and N=258).

  • Assessment of internal consistency and interrater reliability.
  • Correlational analyses with established measures like the Mini-Mental State Examination and DSM-III-R criteria.
  • Factor analysis to determine underlying domains of the scale.

    • Main Results:

    • The NEECHAM Confusion Scale demonstrated high internal consistency and interrater reliability.
    • The scale showed strong correlations with the Mini-Mental State Examination and DSM-III-R positive items.
    • Factor analysis confirmed distinct cognitive/behavioral and physiological domains within the scale.
    • The NEECHAM scale proved effective in identifying acute confusion, including subtle "quiet" manifestations.

    Conclusions:

    • The NEECHAM Confusion Scale is a valid and reliable instrument for bedside assessment of acute confusion in elderly patients.
    • The scale is particularly useful for detecting the onset of confusion and "quiet" presentations.
    • The NEECHAM scale facilitates prompt monitoring and management of acute confusion in a hospital setting.
